Polar Pathfinder - Extended CDR

Configuration Item ID: 01B-24b

The Polar Pathfinder - Extended Climate Data Record (CDR), utilizes the Advanced Very High Resolution Radiometer (AVHRR) and Visible Infrared Imaging Radiometer Suite (VIIRS) instruments and contains several geophysical variables over the Arctic and Antarctic from 1982–present. The data products are mapped to a 25 km Equal-Area Scalable Earth (EASE) grid at two local solar times: 04:00 and 14:00 for the Arctic, and 02:00 and 14:00 for the Antarctic. Using local solar time rather than standard UTC times provides better information on diurnal differences at all locations.

To help the project receive continued support, updates, and improvement, tell us how you use Polar Pathfinder - Extended CDR data by completing our optional User Registration Form.
